,SPECIFICATION forming part of Letters Patent No. 570,123, dated October 27, 1896.

Application filed May 27, 1896. Serial No. 593,336. (No model.)

' provide a simple and comparatively inexpensive one which will be positive and reliable in operation, and to enable the wind to be entirely excluded from the wind-wheel when the windmill is thrown out of operation to prevent the same from beinginjured by high winds or heavy storms.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a Windmill constructed in accordance with this invention, the doors being open to admit Wind to the Wind-Wheel. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a similar View, the doors being closed. Fig. 4 is a vertical sectional view of the windmill. Fig. 5 is a detail sectional view illustrating the construction of the gearing for transmitting motion from the wind-wheel to a pump-rod or the like.

Like numerals of reference designate corresponding parts in all the ligures of the drawings.

l designates a rectangular frame designed to be mounted on a tower or other suitable support and receiving a horizontal wind-Wheel 2, which is mounted loosely on a vertical shaft 3 and which is designed to communicate motion to a pumprod or the like. The frame 1 is composed of a top 4, a bottom 5, and corner posts or uprights 6, and it has mounted between its top and bottom an annular series of posts or supports 7, to which are hinged doors S, arranged in an annular series and admitting, when open, wind to the wind-wheel and entirely excluding Wind from the wheel When they are closed. Each door 8 is hinged lto one post or support 7, and, when closed, its free edge abuts against the adjacent post or i support, and the entire series of doors are simultaneously opened and closed by means of a ring 9, connecting with the doors and with suitable operating mechanism.

When the doors are open, they are adapted to admit the wind to the wind-wheel from any direction which receives the full power of the wind to operate it, but it is not retarded by the same, as the blades 10 of the wind-Wheel, when coming into the Wind, are shut off from the same by the doors until they arrive at a position directly in front of the wind.

The wind-Wheel, which may be of any desired construction, is preferably composed of blades lO, slightly angular in cross-section in order to hold the Wind, and mounted in a suitable frame, consisting of a top 1l and a bottom 12, the blades serving as the means for connecting the top and bottom of .the wind-Wheel frame. The top and bottom of the wind-Wheel frame are preferably provided with radial cleats 13 to enable the ends of the blades to be readily attached to them. The vertical shaft, uponwhich the Wind-wheel is mounted, is designed to be provided with suitable brackets or bearings, so that it will be firmly mounted in proper position.

The ring 9, which is adapted to reciprocate to open and close the doors 8, is mounted in suitable guides 14, consisting of loops of horizontal rods which extend from the uprights or corner-posts 6 of the frame to the adjacent post or supports? of the hinged doors 8, and the ring is connected with the doors by link rods 15. When the doors are open, their outer edges are supported by a ring, which is located at the exterior of the doors, and it prevents any liability of the doors opening too far, as it forms a stop for them. The operating, mechanism for reciprocating the ring to open and close Ithe doors consists of a pair of chains 16, or similar iiexible connections, located at opposite sides of the frame l, attached to the ring, and passing over pulleys 17, which are mounted on the frame. The chains 16 depend from the frame l and eX- tend to the base ot' the supporting-frame or tower, and they are designed to be connected with suitable operatin,f :levers. One chain is adapted to reciprocate the ring in one direction and the other chain in the opposite directlon, and the doors may be quickly oper= IOO ated to expose the wind-wheel to the wind or to exclude the latter from the wind-wheel.

The wind-wheel is provided at its bottom with an eccentric 18, mounted on the lower face ofthe bottom of the wind-wheel frame and consisting of three trian gularly-arran ged rollers mounted in a suitable support or bearing and adapted to engage a reciprocating bar 19. The reciprocating bar 19, which is disposed horizontally and which is located beneath the wind-wheel, is mounted in bearings 2O and 2l, and is provided at its upper face with opposite stops 22, forming a recess, located at opposite sides of the vertical windwheel shaft and receiving the eccentric. The vertical wind-wheel shaft passes through a slot of the reciprocating bar. The bearing 22 is provided with a roller 23 to receive the reciprocating bar, and the latter is connected by a link 24 with one arm of a bell-crank lever 25. The bell-crank lever 25, which is fulcrumed at its angle in a slot or opening of the bottom of the main frame l, has its upper arm arranged in the slot of the reciprocating bar, and its other arm is designed to be connected with a pump-rod or othersuitable device for transmitting motion from the windwheel to the machine or apparatus to be operated. The eccentric may be arranged at any desired distance from the shaft in order to obtain the desired speed or power.

It will be seen that the windmill is simple and comparatively inexpensive in construction, that it is positive and reliable in operation, and that the wind-wheel is adapted to receive the full force and eitect of the wind and may be entirely shut oii from the same.

Changes in the form, proportion, and minor det-ails of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

That I claim is-- l. In a windmilhthe combination of a frame,

a horizontal wind-wheel, an annular series of vertical posts mounted on the frame, an ann ular series of outwardly-opening doors hinged at one edge to the vertical posts and having their other edge free and arranged to abut against the adjacent post in closing a reciprocating horizontally-disposed ring mounted on the frame, encircling the doors and connected with the same, said ring being adapted to open and close the doors, and also forming a stop to limit their outward swing, and means for operatin g the ring, substantially as described.

2. The combination of a frame, a horizontal wind-wheel mounted thereon, horizontally-alined bearings mounted on the frame and located beneath the wind-wheel, one ot' the bearings being provided with a roller, a horizontally-disposed reciprocating bar slidingly mounted in said bearings7 an eccentrically-arran ged rollerdepending from the windwheel and engaging the reciprocating bar, and a bell-crank lever fulcrumed at its angle on the frame and having one arm connected with the reciprocating bar at a point intermediate with the ends thereof, substantially as described.
